Hi,
I have Red Hat Linux 8.0 in my system. I was changing some display resolution in my machine and after the changes, I tried running a program called teapotfly then it is giving me the following error. Any idea of what went wrong or what I could do to solve it.

GLUT:Fatal eror in teapotfly : visual with necessary capabilities not found.

Thanks.

Run glxinfo and see what modes are available. The switch to the one that gives you what you need. You have are defaulting to 16bpp.
